into four boards is called a Quad-XSB. Each composition of physical unit of the
divided PSB is called an eXtended System Board (XSB). These XSBs can be combined
freely to create domains.
DR functions on these servers are performed on an XSB. This manual uses the term
system board unless physical units of PSB and XSB are described. For an explanation
of each term, see
TABLE 1-2 .
Note – This document explains DR functions on system boards. Use the Solaris
command cfgadm(1) to execute DR on I/O devices, including PCI cards. For more
information, please see the service manual for your system, and the cfgadm(1M)
and cfgadm_pci(1M) man pages.
